Application filed May 16, 1921. Serial No. 469,757. 1

To all w/wm it may concern:

Be it known that I, LOUIS B. OLIN, a citizen of the United States, and a resident of Chicago, in the-county of Cook and State of Illinois, have invented certain new and use-- ful Improvements in Refrigerator Vehicles, of which the following is afs pecification.

The invention relatesvto vehicles, and particularly to an improved refrigerator truck for use in distributing and delivering icecream and the ingredients for a cooling mixture, such as ice and salt. l

I have shown and described a refrigerator truck which embodies some of the features shown and described in my pending application for United States Letters Patent, Se rial N umber 403,440, filed August 13, 1920, One of the objects of the invention is the production of a refrigerator truclowhich" will serve to assist in maintaining'the propertemperature of the ice-cream with a Inini-v I mum ice consumption; anothe'r object is to I provide a constriiction and arrangement of parts which will eliminate the necessity of frequent ice' replenishment in the refrigerator section of the vehicle, thereby eifectlng a I saving in labor and elements going to make the .aid of the receptacles.

the cooling, mixture, to wit: ice and salt.

The invention has as a further ob ect the provision of a number of receptacles which or refrigerant, and which are arrangedto surround the cooling chamber produced by The cooling chamber contains compartments. These receptacles are constructed sothatthe ice and I salt mixture with which they are filled, andwhich produce the cooling. medium, cannot possibly reach the ice-cream, or other com mcditv which is being cooled. In the arrangement produced by the invention, the cans and packages containing the ice-cream donot come in contact with the ice, salt, or other cooling mixture, but are cooled in the compartments which are entirely freeof ice and'salt. This is of great importance in view of the tact that the ice used is frequently obtained from surrounding lakes and rivers and contains foreign matter which would injuriously affect the ice-cream in the (\(flflfll'lilt it were to come in contact with the cream. This, of course. would render the icwcreain insanitary, unusable and un-' salable. It is one of the prime objects of the; invention that the cans and packages containing'the ice-cream shall be cooled, but

earenror shall not come in contact withitliecooling mixture; v

In connection with the refrigerator-section of the vehicle, it is an object of the invention to provide storage places for various flavors of ice-cream and for various sizes of,

containers of the ice-cream, these containers usually being metal cans or paper packages. In the vehicle shown-, compartments for the storage of small packages of ice-cream, -'famiharly knownas brick ice-cream, are providedint-he lower part of the refrigerator section '--Larger compartments are provided 1n the intermediate part and a single compacked in metallic cans, 7

Another feature of the invention, and one which particularly distinguishes it from. the pending application referred. to, is the provision of a construction which permits the cooling mixture, or the refrigerant containing receptacles-to be disassembled for the purpose of removing them fro-in the ehicle for repair or other'purposes should this be found" necessary. F

The invention has for a further object, the provision of an arrangement whereby the ice-cream may be readily-accessible without permitting the introduction of relatirelj warmerairto all of the compartments when one of the compartments is opened to remove or fill; the same.

Another of the objects of the invent-ion is to provide a construction and arrangement whereby ice and salt and also ice-cneain are readily accessible from the ground without Inecessitating climbing on and oi? thereiicle,

The invention has for a further object-the '70 'partment is provided in the upper" part for the bulk ice cream, which is usually.

provision of a refrigerator truck,the walls of which are constructed nd so insulated as to maintain "a. temperature in the various compartments of the refrigeraton section,

which will keep the ice-=cresm, or other conn modityconfined therein, in its properconfdh tion.

The vehicle may accommodate and carry, theempty. ice-,

is also constructed so that cream cans and covers therefor,preventing their loss and hiding themtrom View, thus improving the appearance of thevehicle.

The vehicle is further constructedwith salt and ice compartments adapted to carry a large quantity of salt and ice to he supplied to the customers for use in their re frigerators in which ice-cream to be sold by-them is stored and kept in a salable condition. Thesalt container is provided with means for readily filling it from either the top or the side and the container is also provided with an arrangement whereby the salt may be readil removed from the container when this is esired." The ice container, or enclosure, herein before referred to is arranged adjacent the salt container. A means is providedtherein for preventing the water produced by the melting ice in this enclosure from reaching the salt.

A modified arrangement embodying the invention is shown and described in which the cooling chamber in the refrigerator section of the truck is divided by a cooling mixfture receptacle placed transversely to the other cooling mixture receptacles. This arrangement provides for cooling compartments on both sides of the refrigerator section with a cooling mixture receptacle between, and also provides for means of entry to the compartments on both sides of the refrigerator section. In this arrangement, the

7 drawers in the lower. cooling compartments into which ice-cream in brick form is stored are shorter and therefore they maybe moved into and out of their respective compartments in their respective cooling chambers more readily than the long drawers shown and referred to in-the remaining drawings and description. This modified form of refrigerator truck is particularly useful in operating in crowded city streets where space is limited.

The invention will be described in detail and more readily understood when read in conjunction with the accompanying drawings illustrating the invention together with the modified form which has been referred to. It will be obvious that other changes and modifications may be employed without departing from the spirit of the appended claims forming a part hereof.

will he kept in good and salable condition trated in the drawings, the vehicle is provided with a box, or body 13 having walls which are suitably constructed for a vehicle refrigerator and which include suitable insulating material. The body is-mounted upon cross-beams 1 1, which are in turn arranged upon the chassis-15' of the truck which carries the entire structure. The truck isprovided with the usual drivers seat 16 and the canopy 17. At the rear end oft-he vehicle there IS provided a compartment 18 within which may be stored the empty cans which are gathered from the customers. Below the body 13 and adjacent the compartment 18 is arranged a compartment 19 for the reception of the caps or covers removed from the cans stored in the .zompartment 18.

The interior of the body--13 .isprovided with various enclosures, chambers, compartments and receptacles.- In the forward end of the vehicle toward the drivers seat are arranged the enclosures for the ice and salt. Back of these is the refrigerator section of the vehicle which is separated from the ice and salt enclosures by a wall' con structed like the main walls, floor, top and body of the vehicle. This refrigerator section contains the enclosure which in turn.

these receptacles are substantially surrounded by suitable insulating material. Inthe invention shown in Figures 1, 2, 3 and 4 the cooling chamber is shown with removable cooling mixture receptacles on three sides and top andwith suitably insulated top-wall. floor, doors and This insures that the ice-cream irrespective of the temperature outside of the vehicle or the distance of the customers place of business from the central deli-very station.

-The forward portion of one of the side walls of the body 13 is provided with sliding doors 20, 21 and 22. The top of this forward portion is provided with the closure 23. The sliding doors 21 and 222 permit access to the salt container 24 and the sliding door 20 and the closure 223 permit access to the ice compartment or enclosure 25.

The salt container has an inlet 26 whereby necessitating the exposure of theice provided in the enclosure 25. The door 21 may also be utilizedfor this purpose when desired. The door 22 is arranged at a lower level and permits .readyaceess to the salt so that it may be taken from the container 24 from the outside of the vehicle. a

The refrigerator end of the vehicle is provided with swinging doors 27, 28 and 29 which permit access to the compartments of the cooling chamber, which cooling chamber is generally designated 30. This coolingchamber is ,divided into a plurality of separate compartments 31, 32, 33, 34 and 35. The compartments 31, 32, and 33 may receive and aee'ommodate'the, cans of cream.-

The remaining compartments 34 and 35 are of a lesser height and will readily accommodate the sliding drawers 36,37, 38 and 39. These latter compartments are arranged below the compartments 31, 32 and 33 so that they will readily 'permit access thereto to.

insert and remove the bricks of cream while the driver stands on the ground and with out requirin him to climb up on the truck.

The door 2 closes the compartment 31. The "door 28 closes'the compartments 32 and 34. The door 29 closes the compartments 33 and 35. The doors 28 and 29 also allow access to the drawers 36, 37, 38 and 39. It

is therefore apparent that access may be had to the ice-cream, or other'commodity contained in one compartment withoutnecessitating .the. admission of warm air into all the other compartments.

The cooling chamber 30, containing the compartments 31, 32, 33, 34 and 35, is surrounded at three of its sides and at its top by removable or separable metallic recep tacles or containers which form the wallsof these compartments. These receptacles are adapted to contain the refrigerant, or the cooling medium whereby the ice-cream, or other commoditystored in the compartments may be kept in proper condition. These receptacles at the three sides of the cooling chamber 30 are clearly shown in Figure 3 and are designated bythe numerals 40, 41 and 42. These receptacles are 1 adapted to be separated from each other sothat one may be separated or removed'from the vehicle without necessitating the removal of all of them should this at any time be found necessary or desirable. These receptacles aresubstantially rectangular in shape and are each provided with a plurality of transverse walls, or partitions 43, which are channel shaped and held with relation to the side walls of these refrigerant receptacles. These transverse partitions 43 divide the receptacles into separate compartments into which the cooling mixture may be placed and packed to cool the cooling chamber 30 and its compartments.

It has been found in actual practice that very good results in refrigeration have been or compartments. These partitions tend to. y keep the mixture in compact masses in their respective divisions, or compartments and practically free of independent movement although in normal use the vehicle is subjected toa great amount of vibration and strain.

A drain pipe 44 leads from the bottom of each of these receptacles and extends through the lower floor board 45 of the vehicle. These drain pipes relieve the receptacles of the brine which. results from. the melting of themixture.

The transverse partitions 43 of the mixture receptacles do. not extend the full length thereof either at the top orthe bottom, as shown at 43* and 43 in Figures 2 and 4. At the top they provide room for the downwardly projecting flanges 46 of the uppermost mixture receptacle 47. At the bottom the transverse partitions 43' are terminated a sufi'icient distance above the bottoms of the mixture receptacles 40, 41, and 42 to permit free circulation of brine to. the drain pipes 44, The mixture receptacle 47 provides the top wall of the cooling chamber 30. The flanges 46 surround three openings 48, 4t) and 50in the bottom of the mixture receptacle 47. These openings communicate with the tops of the receptacles 40, 41 and 42. The flanges 46 substantially conform in outline to the openings and last named receptacles. The flanges 46 also assist in holding the receptacle 47 with respect-to thereceptacles 40. 41 and 42 from the side walls of the cooling chamber. In addition, the flanges 46 prevent water or brine from finding its way into the cooling chamber 30. The receptacle 47 is. substantiallyrectangular in out- 11 line and is provided at its uppermost edge with the circumferential laterally extending flange 51 which rests uponthe inner walls 52, 54 and 55 of the refrigerator enclosure of the vehicle which surround the 115,

closures.

The cooling chamber 30 is divided to produce aplurality of compartments and therefore the chamber is provided with horizontal 130 partitions 60 and 61 and vertical partitions 62, 63 and 64.. The partitions 60 and 6]. are

\ removably secured to the sidewalls of the bottom of the cooling chamber 30, is utilized for the accommodation of the drawers 36, 37, 38 and 39. This space is divided by the jvertical channel iron partitions 63 and 64 which rest upon theupperfloor boards 67 and support the partition 62 at the center line thereof. By reason of the fact that the partition 62 isv arranged immediately above the partitions 63 and 64, the whole interior structure of the cooling chamber is supported. j From the foregoing description, it is evident that by unscrewing the wood screws 58 the receptacle 47 maybe lifted away from the sub-structure of the cooling chamber 30, and by undoing the bolts and nuts which bindthe parts 60 and 61 to the angle iron strips 65 and 66, these partitions may also be lifted away, or removed from between the inner walls of the refrigerant containers 40. 4.1 and 42. The partitions 62, 63' and 64 may also-bedisconnected and removed fro1n*be tween the walls of the refrigerant contaiuf ers.- The removal of these partitions allows either one orall of these containers to be removed from the vehicle and replaced in the event that repairs-or replacement of the containers becomes necessary. These refrig erant containers 40; 41 and 42 are surrounded by the insulated walls 68, 69, 70 and 59 wl'iich include the inner wall portions 52. 53 54 and 65 the insulating material 71 and the outer wall portions 72. 73, 7 4 and 7 5 and the top and bottom floor boards and 67. The

wall 70 is provided with the doors 27, 28 and 29 which are also insulated. These walls may be of any desired construction and may include the cross-beams 76. 77 and 78 which close the endsof these walls and prevent any material from finding its way between them. The uppermost wall of the box or body 7 above the cooling chamber 30 is provided with an opening which is closed by two insulated hinged closures 7 9 and 80 hinged at 81 and 82 respectively, which are provided toallow the refrigerant receptacles to be filled with the refrigerant. The closures are provided with the handles 83 and 84 where by they may be readily opened and closed. The edges of these closures engage and rest upon the sides of the opening and are thereby limited in their movement inv an inward direction. A strip 85 is provided to seal the juncture of these closures. It is evident that when these closures are opened the cooling chassis 15.

being driven throughthe streets.

mixture ma be packed in the receptacles 40; 41, 4.2 and 47. If desired these receptacles maybe lifted out of the refrigerator section within which they are arranged when the partitions 60, 61 and 62 and other portions of the structure such as the angle iron supports 65 "and 66 are detached therefrom.

. The outer walls of the box or body may be secured to the remainder of the structure in any suitable manner. That herein shown for securing them in place includes the longitudinally extending parallel beams 86 and 87 arranged adjacent the top of the structure, the sill-beams 88 and 89- arranged at the lowermost part of the'box or body and theintermediate beam90. The sill-beams 88 and 89 rest'upon and are supported by the transverse beams 14 which are in turn secured to the p-arallel under-sills-91 which rest upon the channel beams 92 of the These transverse beams extend beyond the sides of the box or body. to provide asupport for the running boards 93 and 94 which are arranged upon the opposite sides of the body and preferably extend from one end to the other thereof. The running board 94 is provided with a hinged extension 95 and provides 'a iwider portion for the driver to stand upon when removing the cans from within the coolingl chamber. These last named running boards 94 and 95 may be provided with abutments 96 which abut against each other and assist in maintaining the hinged or swinging board 95 in the position shown in Figure 4.

The rearmost end of the vehicle is, as be fore stated, provided with a compartment 18 for the accommodation of the empty cans which are gathered fromthe customers. This compartment is composed of the side walls 97 and 98 and the inclined floor 99. The end of this portion is open excepting it is closed by a curtain 100 which is supported by means of the'wires or cords 1'01 and 102 which have their opposite ends res ectively' connected to the bars 103 and 104."

us end of? this curtain is secured to one of the bars 103 and the opposite end is free to be raisedand lowered upon the wire or cords 101 and 102, which wires-or cords are threaded through theopeningsldfi pro-= .vided in this curtain 100. When it is de-- tion and thereby hidethe empty cans con- The curtain tained in the compartment. and support structure also assist in preventing a loss. of cans from the compartment due to jarring and jolting'of thevehicle while As before stated, the forward end of the body 13 is provided with a salt containing compartment 24 and the ice compartment 25. The .'ice used is usually in the form of chips which may be inserted through the opening closed by the closure 23 and removed therefrom through the opening closed by the door 20. The walls forming this end of the vehicle body are also insulated so that the ice contained in the compartment 25 will not readily melt while being conveyed through the streets. A metallic pan, having a drain 107 is arranged in the bottom of this compartment and is provided to prevent the water, which naturally would result from the melting of the ice in the compartment 25, from finding its way into thesalt container 24; It is of course understood that this pan 106 has an opening which permits of access to the ice throu h the door 20. The salt container 24, as be ore stated, is provided with an opening 26 which terminates outside of the uppermost wall of the vehicle body and connects with a chute 108 leading downwardly from the opening into the container 24. A closure 109 is provided for this chute. Thus it can be readily seen that this container can be easily filled from the top through this opening 26 without exposing the ice contained in the compartment 25, or may be filled through the opening which is closed by the sliding door 21. The salt in this container may be removed therefrom through the opening closed by the sliding door 22 This salt con'ipartment 24 may be constructed of the walls 110 and be provided with a metallic roof 111 which is preferably sloped so that it will shed the ice and water as the former is removed from the compartment 25.

Figure 8 discloses a modified arrangement of a refrigerator vehicle of which the invention is susceptible. In this construction the opposite sides of. the. vehicle body ,are provided with a plurality of openings and closures 112, 113, 114 and 115. This structure embodies-the removable receptacles 116, 117 and 118 for the refrigerant. The refrigerant receptacles 116, 117 and 118 are provided with partitions which are constructed similarly to the partitions in the structure hereinbefore described. The container, or receptacle 118 is arranged transversely to the receptacles 116 and 117 and is positioned in this manner to provide cooling chambers on opposite sides thereof. These coolin chambers are again sub-divided to I)I(Wl( e a plurality of tiers of; compartments to accommodate the cans of ice-cream and also to enclose drawers which extend from the side walls of the body to the transversely arranged refrigerant receptacle 118. it is understood that the vertically arranged refrigerant receptacles in this structure rest upon the floor of the refrigerator section and have their uppermost open ends in communication with the horizontally arranged refrigerant receptacle 119. This latter receptacle is provided with flanged openings 120, 121 and 122, the flanges of which telescope into the respective refrigerant receptacles 116, 117 and 118.. The flanges which fit into the receptacles 116, 117 and 118 are the flanges 123 at the bottom of the refrigerant receptacle 119. This receptacle is also provided at its uppermost edge with the circumferential laterally extending flange 124. This flange rests upon the inner wall boards 125, 126, 127 and 128 of the refrigerant enclosure. The tiers of compartments are produced by the removable vertical partitions 129, and 130 and the horizontal partitions 131, 132, 133 and 134 which are supported in position by means of guide ways 135 secured to the trans versely arranged refrigerant container 118 and to two of the side walls of the refrigerator section. Angle iron supports 136 are secured, as by rivets 137, to the refrigerant containers 116, 117 and 118 and the re- .compartments 141 and 142 are shown parts of the lower compartments 143. and 144. It will be understood that there are similar compartments below the compartments 139 and 140. It will also be understood that the same .form ofconstruction may be used for other compartments above these shown in the figure referred to.

The refrigerant receptacle 119 is also provided with the angle iron -braces 145 and 146.

It will be seen that the cooling mixture may be introduced into the refrigerant receptacles 116, 117 and 118 through the openings 1'20, 121 and 122 without necessitating the'removal of the receptacle 119 when any or allot them need filling.

In this modified structure the vehicle has running boards on opposite sides of the. body. The running board 147 is provided with the hinged extension 148 and the running board- 149'is provided with the hinged extension 150. These provide wider portions for the driver to stand. upon when removing the cans from within the cooling chambers. It isunderstoodthat these runningboards may be provided with proper, abutments to assist in maintamlng hinged extensions in the position shown in Figure 8.
